It is almost like they should start selling sunglasses over the counter; like in pharmacies - and they should put precautionary warnings on them. Kind of like you see on your passenger side mirror in a car. It is visible but doesn't take up so much space that you can't see - and it should read, "Warning these sunglasses are scientifically proven to make whomever is wearing them look better, if you are fooled we retain no responsibility for your ignorance."
That would be great. Really. It might just make my day.
If you really think about it, it is obvious people know. No longer are sunglasses purchased merely to protect our fragile eyes from the vicious sun. No, now most people don't even buy sunglasses for that purpose. They just want to look better, and the quick fix is sunglasses. The whole ultraviolet ray protection is just an afterthought. How many times do you see people wearing sunglasses when it isn't even necessary? In the dark, in a building, on a cloudy day!? It is ludicrous people - but it sure does work. Maybe I need to get some sunglasses...
